A U.S. teenager who was attempting to set a record for an around-the-world flight was killed when his plane crashed in the Pacific Ocean, and crews were searching Wednesday for his father, who was also onboard.

Family spokeswoman Annie Hayat said the plane flown by 17-year-old Haris Suleman went down shortly after leaving Pago Pago in American Samoa Tuesday night. Hayat said the body of Haris Suleman had been recovered, but crews were still looking for Pakistani-born Babar Suleman.

The teenager's sister, Hiba Suleman, said the trip had been a dream of her father's for years and that her brother was also excited about it. Haris Suleman had recently obtained his pilot's license and instrument rating, which authorized him to fly an aircraft over oceans, and planned to be the pilot in command except in an emergency.

Hiba Suleman told reporters Wednesday that her father and brother had undergone training in how to handle an ocean landing and wore protective suits while flying over water. She said it was unusual for them to take off at night but didn't know whether that contributed to the crash.

"With a trip like this, there's always a risk, and they did prepare for that risk. You can plan all you want, but sometimes things just don't happen the way you planned," she said.

The Sulemans left Indiana state on June 19 in hopes of making the trip in 30 days to set the record for the fastest circumnavigation around the world in a single-engine airplane with the youngest pilot in command to do so. The father and son were using the trip to raise money for the Citizens Foundation, a non-profit that builds schools in Pakistan.

They missed the 30-day timetable, in part due to food-borne illness, but planned to return home Sunday.

Federal Aviation Administration spokesman Ian Gregor in Los Angeles said the single-engine Hawker Beechcraft plane crashed into the ocean Tuesday night under unknown circumstances. The tail number provided by the FAA shows the plane is registered to a limited liability company whose address matches Babar Suleman's home address in Plainfield, Indiana.

U.S. Coast Guard spokeswoman Petty Officer Melissa McKenzie said witnesses reported seeing the Honolulu-bound plane crash about a mile from shore shortly after taking off from Pago Pago International Airport.

The Sulemans had made stops throughout Europe, Africa, Asia and the South Pacific, and the teenager told The Indianapolis Star earlier this month that he was enjoying each visit.

"There is so much beauty and culture in each country that I couldn't possibly witness all that I want to in the span of two days," he said in an email to the newspaper. "That's the maximum time we've been able to spend at a stop."
